TECHNICAL FIELD

Embodiments of the present invention relate to communications technologies, and in particular, to a data query method supporting a natural language, an open platform, and a user terminal.

BACKGROUND

In an Internet era, a service provided by a third-party content provider is encapsulated into a series of data interfaces that can be easily recognized by a computer, and the data interfaces are opened for use by a developer. This behavior is referred to as an open application programming interface (API), and a platform that provides the open API is referred to as an open platform. By using the open platform, the third-party content provider can not only provide simple access to a Web web page, but also perform complex data interaction.

A current open platform generally provides only openness of data; for a large quantity of existing query requests described by a user in a natural language, a content source needs to be prepared in advance, or a specific third-party content provider needs to be invoked according to a fixed API, so that a third-party content provider that supports a natural language query determines, according to a query statement described in a natural language, a service that can be provided in a content source prepared in advance by the third-party content provider, and sends a query response message to the open platform.

In the prior art, there is a small quantity of third-party content providers that support a natural language query; therefore, compatibility between an open platform and a third-party content provider is not high, and in addition, when performing a natural language query based on the open platform, a user cannot appoint a third-party content provider according to a will of the user, which leads to relatively poor user experience.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

To make objectives, technical solutions, and advantages of embodiments of the present invention clearer, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

FIG. 1 is a schematic diagram of an application scenario of a data query supporting a natural language according to the present invention. It should be noted that, the natural language is used relative to a logic language. The logic language is a communication tool used between a human brain and a computer, and the natural language is a communication tool used between human brains. In terms of a form, the natural language generally includes characters (for example, a Chinese character, a phrase, and punctuation) of specific semantics or syntax, or a context. In a specific embodiment, the natural language may be understood as a voice, for example, an utterance that a user says. In a specific implementation process, when the user needs to acquire a service provided by a third-party content provider, the user may input, into a user terminal by using a voice assistant of the user terminal, a query request described in the natural language. The user terminal generates a natural language query statement in a text form from the query request described in the natural language in a voice form, and sends the natural language query statement to an open platform. The open platform sends the natural language query statement that can be recognized to a third-party content provider that performs successful registration. When the third-party content provider returns a query response message to the open platform, the third-party content provider feeds back the query response message to the user terminal, so that the user acquires corresponding service content. A specific process is as follows.

1. The user terminal acquires a query request that is described by the user in the natural language and that is input by using a voice, for example: A. Help me find a restaurant near the science and technology park, or B. I want to watch a romance.

2. The open platform acquires a natural language query statement input by the user terminal.

3. The open platform transforms the natural language query statement into a query statement that can be recognized by a third-party content provider.

4. The open platform determines one or more third-party content providers that the user pays attention to.

5. After determining the one or more third-party content providers that the user pays attention to, the open platform sends the query statement that can be recognized to a corresponding third-party content provider.

6. The open platform receives a query response message returned by the third-party content provider.

7. The open platform returns the query response message to the user terminal.

Persons skilled in the art may understand that, in an embodiment shown in FIG. 1, the open platform may be a computer, a server, or a cluster system integrated with a software algorithm. An application programming interface (API) or a function (function) of the open platform is opened for use by a third-party developer, and the third-party content provider accesses the open platform by using a registration mechanism, and provides a service for the user terminal under scheduling of the open platform. Executors of the third-party content provider may be specifically various network devices of the third-party content provider. A specific type of the network device is not specially limited herein in this embodiment.

FIG. 2 is a schematic diagram of an architecture of an open platform according to an embodiment of the present invention. The open platform provided in this embodiment may be applied to the application scenario shown in the embodiment in FIG. 1. The open platform provided in this embodiment includes: a user access module, responsible for inputting, into the open platform, a natural language query statement sent by a user terminal, and returning a query response message to the user terminal; an interface module, configured to: interconnect with a third-party content provider by using an open API, send a query statement that can be recognized to the third-party content provider, and acquire a query response message returned by the third-party content provider; a natural language parsing module, responsible for transforming the natural language query statement into the query statement that can be recognized by the third-party content provider; and a service scheduling module, which is a control module of the open platform and is configured to: send the natural language query statement to the natural language parsing module; send, according to information about a third-party content provider that a user chooses to pay attention to and information about a third-party content provider that performs successful registration, the query statement that can be recognized to the third-party content provider; and return the query response message to the user access module; the information about the third-party content provider that has performed successful registration, where a third-party content provider that has performed successfully registration and accessed the open platform is saved, and the information may be implemented in a list manner; and the information about the third-party content provider that the user pays attention to, where the user chooses, by using the user terminal, the third-party content provider that the user pays attention to, the user terminal generates, according to a choosing operation of the user, the information about the third-party content provider that the user pays attention to, and the open platform acquires the information; and the information may be implemented in a list manner.

The following describes in detail, by using a detailed embodiment and with reference to FIG. 1 and FIG. 2, a data query method supporting a natural language on the open platform in this embodiment.

FIG. 3 is a flowchart of Embodiment 1 of a data query method supporting a natural language according to the present invention. This embodiment is executed by an open platform, and the open platform can be run on various servers. The data query method supporting a natural language is implemented by using a processing function of the server. As shown in FIG. 3, the method in this embodiment may include the following steps:

Step 301: An open platform receives a natural language query statement sent by a user terminal, and transforms the natural language query statement into a query statement that can be recognized by a third-party content provider.

The natural language query statement is generated after the user terminal receives a query request described by a user in a natural language.

Step 302: The open platform sends the query statement that can be recognized to one or more third-party content providers.

Step 303: The open platform receives one or more query response messages returned by the one or more third-party content providers according to the query statement that can be recognized.

Step 304: The open platform sends the one or more query response messages to the user terminal.

In a specific application process, a third-party content provider accesses the open platform by using a registration mechanism of the open platform. Specifically, the open platform receives an authentication access request message sent by the third-party content provider, where the authentication access request message includes registration information of the third-party content provider, and the registration information may be, for example, registration information about whether the third-party content provider participates in bidding ranking, or participates in optimal matching. After the third-party content provider passes authentication, that is, the third-party content provider performs successful registration, an authentication access response message is sent to the third-party content provider. In a specific embodiment, after the third-party content provider registers with the open platform and passes authentication, the third-party content provider downloads an access specification and a relevant software development kit (SDK) from the open platform, and then the third-party content provider submits, to the open platform according to the specification, an open API provided by the open platform and used by the third-party content provider. At this time, the third-party content provider can provide a service for the user terminal by using the open platform.

For the user, when the user needs to acquire a corresponding service provided by a third-party content provider, the user inputs a query request described in the natural language into the user terminal by using a voice, for example, “Is there anything good to eat nearby”; then the user terminal transforms, by using a voice recognition function, the query request described in the natural language into a natural language query statement. In step 301, the open platform acquires the natural language query statement “Is there anything good to eat nearby” input by the user terminal. The query request that is described in the natural language and is involved in this embodiment mainly refers to a language daily used by people.

Then, the open platform transforms the natural language query statement “Is there anything good to eat nearby” into a query statement that can be recognized by the third-party content provider. Persons skilled in the art may understand that, the open platform can extract useful information from “Is there anything good to eat nearby”. For example, automatic index word extraction, filtering, retrieval, automatic important information extraction, or automatic abstraction is performed on a natural language text. In this embodiment, the query statement that can be recognized refers to a key word or a parameter that has no ambiguity and that can be recognized by the third-party content provider without performing a natural language processing process by the third-party content provider. In a specific implementation process, the natural language query statement may be processed by using a natural language processing method. Specifically, the natural language query statement may be transformed into a key word and a parameter that can be recognized by the third-party content provider. For example, “Is there anything good to eat nearby” is transformed into key words “distance less than 1 kilometer” and “food”, so that the third-party content provider does not need to analyze the natural language query statement, and only needs to perform matching processing between the key words “distance less than 1 kilometer” and “food” in the query statement that can be recognized and an existing shop condition, and chooses an appropriate shop. Persons skilled in the art may understand that, the third-party content provider stores key word information of shops and the like; a query response message that needs to be returned to the open platform may be determined according to key word matching, where the query response message may include a shop name, a shop location, a product price, product performance, word of mouth of a product, and the like. When the third-party content provider performs matching according to the key words and the matching fails, the query response message may include information indicating a query failure or information indicating that a service fails to be provided.

In step 302, the open platform sends the query statement that can be recognized to one or more third-party content providers that perform successful registration. Any third-party content provider is used as an example for description. After acquiring the query statement that can be recognized and that is sent by the open platform, the third-party content provider determines a nearby shop that is relevant to food; the third-party content provider returns a query response message corresponding to the query statement that can be recognized to the open platform, where the query response message includes a shop name, a shop location, food introduction, and the like.

In step 303, the open platform receives the one or more query response messages returned by the one or more third-party content providers according to the query statement that can be recognized. Finally, in step 304, the open platform sends the one or more query response messages to the user terminal.

In the data query method supporting a natural language provided in this embodiment of the present invention, an open platform receives a natural language query statement sent by a user terminal, and transforms the natural language query statement into a query statement that can be recognized by a third-party content provider, where the natural language query statement is generated after the user terminal receives a query request described by a user in the natural language; sends the query statement that can be recognized to one or more third-party content providers; receives one or more query response messages returned by the one or more third-party content providers according to the query statement that can be recognized; and sends the one or more query response messages to the user terminal. In this embodiment, the open platform transforms the natural language query statement into the query statement that can be recognized by the third-party content provider, and the third-party content provider does not need to have a natural language processing capability; an interface may be directly opened for the third-party content provider to perform integration, which reduces an access difficulty in accessing the open platform by the third-party content provider.

Optionally, with reference to FIG. 1, before step 302, step 4 in the embodiment in FIG. 1 is further performed, so that the open platform determines a third-party content provider that can recognize the query statement. In a specific implementation process, the open platform determines one or more third-party content providers that the user pays attention to, and the one or more third-party content providers that the user pays attention to are third-party content providers that are determined by the open platform and that can recognize the query statement. The open platform determines, specifically in the following possible implementation manners, the one or more third-party content providers that the user pays attention to.

One possible implementation manner is: the open platform performs semantic analysis on the natural language query statement, to determine the one or more third-party content providers that the user pays attention to.

In a specific implementation manner, the open platform performs semantic analysis on the natural language query statement, and determines whether the natural language query statement includes an identifier of a third-party content provider. If the natural language query statement includes the identifier of the third-party content provider, the open platform may determine, according to the identifier that is of the third-party content provider and that is included in the natural query statement, the one or more third-party content providers that the user pays attention to. A specific embodiment is used as an example for detailed description. The open platform returns, to the user terminal, a third-party content provider that performs successful registration, and the user may pay attention to a third-party content provider in the third-party content provider that performs successful registration. When the open platform acquires the natural language query statement, for example, the acquired natural language query statement is “search a third-party content provider A for a nearby cake shop”, the open platform determines, by means of semantic analysis, that the natural language query statement includes the “third-party content provider A”, and in this case, the open platform performs matching on the third-party content provider that performs successful registration, and determines whether the natural language query statement includes the “third-party content provider A”. In this embodiment, if it is determined that the natural language query statement includes the “third-party content provider A”, the open platform sends a query statement that can be recognized to the “third-party content provider A”, and acquires a query response message returned by the “third-party content provider A”. Persons skilled in the art may understand that, the natural language query statement of the user may include multiple third-party content providers, and in this case, the third-party content providers acquire multiple query response messages. If the natural language query statement does not include a third-party content provider that the user pays attention to, the open platform sends the query statement that can be recognized to all third-party content providers that perform successful registration, and acquires query response messages returned by all the third-party content providers that perform successful registration.

Another possible implementation manner is: the open platform sends, to the user terminal, a first message used to indicate a third-party content provider that has successfully registered with the open platform, so that the user terminal displays, according to the first message, a list of the third-party content provider that has successfully registered with the open platform; receives a second message that is sent by the user terminal and that is used to indicate a third-party content provider that the user chooses to pay attention to; and determines, according to the second message, the one or more third-party content providers that the user pays attention to, where the second message is generated by the user terminal according to a choosing operation performed on the list of the third-party content provider by the user.

In a specific implementation process, the open platform sends the first information to the user terminal, where the first information includes the third-party content provider that performs successful registration. Optionally, the first information may be implemented in a list form, and the list includes an identifier of the third-party content provider that performs successful registration. After acquiring the first information, the user terminal displays, to the user by using a display interface and according to the first information, the list of the third-party content provider that performs successful registration, and the user may choose a third-party content provider that the user prefers from the list of the third-party content provider that performs successful registration. The user terminal generates the second information according to the choosing operation performed on the list of the third-party content provider by the user, where the second information includes an identifier of the third-party content provider that the user pays attention to. Optionally, the second information may be implemented in a list form. For example, the second information includes third-party content providers such as a “third-party content provider A”, a “third-party content provider B”, and a “third-party content provider C” that the user pays attention to. The open platform may determine, according to the second information, the one or more third-party content providers that the user pays attention to.

In the foregoing two possible implementation manners, accordingly, the open platform sends, according to the one or more third-party content providers that the user pays attention to, the query statement that can be recognized to the one or more third-party content providers that the user pays attention to.

In this embodiment, it is implemented that the user pays attention to the third-party content provider in a self-defining manner, so that the user can voluntarily choose a third-party content provider that the user prefers.

Optionally, based on the foregoing embodiments, that the open platform transforms the natural language query statement into a query statement that can be recognized by a third-party content provider includes: performing, by the open platform, semantic analysis on the natural language query statement to determine a third-party content provider type corresponding to the natural language query statement; and

transforming, by the open platform according to the third-party content provider type corresponding to the natural language query statement, the natural language query statement into a query statement that can be recognized by a third-party content provider belonging to the third-party content provider type.

That the open platform sends the query statement that can be recognized to one or more third-party content providers includes:

sending, by the open platform to one or more third-party content providers belonging to the third-party content provider type, the query statement that can be recognized by the third-party content provider belonging to the third-party content provider type.

In a specific implementation process, the open platform performs semantic analysis on the acquired natural language query statement. For example, semantic analysis is performed on “Help me find a restaurant near the science and technology park”, and a third-party content provider type is determined as a third-party content provider of a life encyclopedia type. In this case, the open platform transforms the “Help me find a restaurant near the science and technology park” into query statements “food”, “restaurant”, and “science and technology park” that can be recognized by a third-party content provider belonging to the third-party content provider of the life encyclopedia type, and then sends the query statements “food”, “restaurant”, and “science and technology park” that can be recognized to one or more third-party content providers that perform successful registration and that belong to the third-party content provider of the life encyclopedia type, and acquires one or more query response messages returned by the third-party content provider of the life encyclopedia type.

For another example, semantic analysis is performed on “I want to watch a romance”, and a third-party content provider type is determined as a third-party content provider of a film and television data type. In this case, the open platform transforms the “I want to watch a romance” into query statements “film” and “romance” that can be recognized by a third-party content provider belonging to the third-party content provider of the film and television data type; and then sends the query statements “film” and “romance” that can be recognized to a third-party content provider that performs successful registration and that belongs to the third-party content provider of the film and television data type, and acquires one or more query response messages returned by the third-party content provider of the film and television data type.

In this embodiment of the present invention, semantic analysis is performed on a natural language query statement, and a query statement that can be recognized is sent to a specific third-party content provider, which reduces signaling interaction and improves processing efficiency of an open platform.

Optionally, with reference to FIG. 1, when the open platform sends the query statement that can be recognized to multiple third-party content providers, and acquires multiple query response messages, there is a problem of how to return the multiple query response messages to the user terminal. Therefore, before step 304, that is, before the open platform sends the multiple query response messages to the user terminal, or that is, before step 7 in the scenario embodiment in FIG. 1, the open platform sends the multiple query response messages to the user terminal according to a scheduling policy. Specifically, the open platform determines, according to registration information of the multiple third-party content providers, the scheduling policy according to which the multiple query response messages returned by the multiple third-party content providers are sent to the user terminal. The scheduling policy may include a bidding rank scheduling policy, a matching degree scheduling policy, a word-of-mouth scheduling policy, and the like. A specific scheduling policy is not specially limited herein in this embodiment. When sending the multiple query response messages to the user terminal, the open platform specifically sequences the multiple query response messages according to the scheduling policy, and sends the multiple query response messages to the user terminal according to a sequencing result. The following possible implementation manners may be included.

One possible implementation manner is: the open platform sends the multiple query response messages to the user terminal according to bidding ranks of the multiple third-party content providers.

Specifically, according to registration information about whether the multiple third-party content providers participate in bidding ranking, a bidding rank scheduling policy according to which query response messages returned by third-party content providers that participate in bidding ranking are sent to the user terminal is determined. The multiple query response messages are sequenced according to the bidding rank scheduling policy and bidding ranks of the third-party content providers, and the multiple query response messages are sent to the user terminal according to a sequencing result.

A specific embodiment is used as an example. If the registration information about the multiple third-party content providers includes bidding information of food, that is, key word purchase of food, the open platform sequences the query response messages according to bidding ranks of the third-party content providers, that is, money paid for the purchase, and preferentially sends, to the user terminal, a query response message returned by a third-party content provider that has a high bidding rank. The user terminal preferentially displays a query response message that has a high bidding rank to the user. For example, the open platform sends, to the user terminal according to a sequencing result, three query response messages that have top three bidding ranks, and the user terminal displays only the three query response messages. Alternatively, the open platform sends, to the user terminal according to a sequencing result, the query response messages and priorities of the query response messages, and the user terminal displays the query response messages to the user in order according to the priorities.

Another possible implementation manner is: the open platform determines a matching degree between a query response message returned by each of the third-party content providers and the natural language query statement, and the open platform sends the multiple query response messages to the user terminal in descending order of matching degrees between the multiple query response messages and the natural language query statement.

Specifically, the matching degrees between the query response messages returned by the third-party content providers and the natural language query statement are determined according to registration information about whether the multiple third-party content providers participate in optimal matching. An optimal matching scheduling policy according to which query response messages are sent to the user terminal is determined according to the matching degrees. The multiple query response messages are sequenced according to the optimal matching scheduling policy and in descending order of the matching degrees between the query response messages and the natural language query statement, and the multiple query response messages are sent to the user terminal according to a sequencing result.

The matching degree includes at least one of the following: a distance matching degree, a price matching degree, or a product matching degree.

In the following, a specific embodiment is used as an example for detailed description.

When the matching degree is a distance matching degree, and the registration information of the multiple third-party content providers includes information indicating that the multiple third-party content providers participate in optimal matching and the matching degree is the distance matching degree, the open platform sequences distances between the user terminal and shop locations in returned query response messages, and preferentially sends, to the user terminal, a query response message returned by a third-party content provider that has a shortest distance from the user terminal, and the user terminal preferentially displays the query response message that has the shortest distance. Alternatively, the open platform sends query response messages and priorities of the query response messages to the user terminal according to a sequencing result, and the user terminal displays the query response messages to the user in order according to the priorities.

When the matching degree is a product matching degree, and the registration information of the multiple third-party content providers includes information indicating that the multiple third-party content providers participate in optimal matching and the matching degree is product matching, the open platform extracts key words from returned query response messages, performs matching between the key words and the natural language query statement, and preferentially sends, to the user terminal, a query response message that is returned by a third-party content provider and that has a highest matching degree, and the user terminal preferentially displays the query response message that has the highest matching degree. Alternatively, the open platform sends query response messages and priorities of the query response messages to the user terminal according to a sequencing result, and the user terminal displays the query response messages to the user in order according to the priorities.

When the matching degree is a price matching degree, and the registration information of the multiple third-party content providers includes information indicating that the multiple third-party content providers participate in optimal matching and the matching degree is price matching, the open platform extracts price information from returned query response messages, sequences prices, and preferentially sends, to the user terminal, a query response message returned by a third-party content provider that has a lowest price, and the user terminal preferentially displays the query response message that has a highest matching degree. Alternatively, the open platform sends query response messages and priorities of the query response messages to the user terminal according to a sequencing result, and the user terminal displays the query response messages to the user in order according to the priorities.

In this embodiment of the present invention, an open platform sends a query response message to a user terminal according to a scheduling policy. Therefore, not only an optimal query response result is provided for the user terminal, but also a third-party content provider can improve service quality and improve user experience.

This embodiment is executed by a user terminal, and the user terminal may be specifically a smart phone, a tablet computer, or the like. The data query method supporting a natural language provided in this embodiment may be implemented together with a method applied to an open platform side. As shown in FIG. 4, the method in this embodiment may include the following steps:

Step 401: A user terminal receives a query request described by a user in a natural language.

Step 402: The user terminal generates a natural language query statement according to the query request described by the user in the natural language.

The open platform sends the query statement that can be recognized to the one or more third-party content providers, and then receives the query response message returned by the one or more third-party content providers.

Then, the user terminal receives the one or more query response messages sent by the open platform. In a specific implementation process, when there are multiple query response messages, the user terminal displays the query response messages on a display interface of the user terminal according to an order of receiving the query response messages sent by the open platform; or the user terminal displays, according to the query response messages and priorities of the query response messages that are sent by the open platform, the query response messages on a display interface in a priority sequence.

Optionally, before the receiving, by the user terminal, one or more query response messages that are returned by the one or more third-party content providers and that are sent by the open platform, the method further includes:

receiving, by the user terminal, a first message that is sent by the open platform and that is used to indicate a third-party content provider that has successfully registered with the open platform;
